What Happens to Your HSA at Death: Spouse vs. Anyone Else

Margaret, 71, is a widow living in Scottsdale, Arizona. She files single, draws about $58,000 a year from Social Security and a traditional IRA, and has built her HSA to $92,000 by paying medical bills out of pocket for two decades. Her only heir is her son, David, a 44-year-old software engineer who earns about $100,000 and files single — solidly inside the 24% federal bracket (single 24% band: $103,351–$197,300 for 2026). Margaret’s beneficiary form still lists her late husband. If she does nothing and David inherits the HSA, the entire $92,000 lands on his tax return as ordinary income the year she dies. Stacked on his $100,000 salary, the combined $192,000 stays inside that 24% band, so the $92,000 is taxed at 24% — roughly $22,080 in federal tax in a single year, on top of his salary. The fix costs her nothing but a phone call — and the difference between the best and worst outcome here is the whole article.

The decision in one sentence

Your HSA does not have a beneficiary problem and a tax problem. It has one problem, and it is the same problem: who you name decides the tax. A spouse beneficiary is the only person on earth who can inherit an HSA and keep it as an HSA. Everyone else triggers a full taxable termination. So the practical question is not “how do I minimize HSA estate tax” — it is “is my beneficiary my spouse, a non-spouse, or (by default) my estate,” and each answer carries a completely different result.

Spouse beneficiary: the best outcome, by a wide margin

Under IRC §223(f)(8)(A), if your surviving spouse is the named beneficiary, the HSA simply becomes their own HSA. Not an inherited account. Not a beneficiary account with a clock on it. Their account, treated as though they had owned it all along.

• Zero tax at transfer. Nothing is reported as income. The balance moves over intact.
• No 20% penalty, ever, on qualified use. Your spouse spends it tax-free on qualified medical expenses for the rest of their life.
• No HDHP requirement. Your spouse does not need to be enrolled in a High-Deductible Health Plan to keep or use the inherited HSA. They only need an active HDHP to make new contributions — not to hold the balance.
• Full IRA-like flexibility after 65. Once your spouse is 65+, non-medical withdrawals are taxed at ordinary income rates with no penalty — exactly like a traditional IRA distribution.

This is the cleanest inheritance in the entire tax code for a tax-advantaged account. Unlike an inherited IRA, there is no 10-year drain rule (SECURE Act §401, IRC §401(a)(9)(H)) and no required-minimum-distribution schedule. If your spouse is alive and you want them to have the money, naming them is not just the best HSA choice — it is the only one that preserves the account’s entire lifetime advantage.

Non-spouse beneficiary: the account dies with you

Name a child, a sibling, a parent, a friend, or a trust, and IRC §223(f)(8)(B) controls. Because a non-spouse cannot legally own an HSA, the account ceases to be an HSA on the date of your death. The custodian distributes the fair-market value to your beneficiary, and that full amount is ordinary taxable income to them in the year you die.

Two things people get wrong here:

1. There is no 20% penalty. The additional 20% tax under IRC §223(f)(4) is waived on death. People hear “no penalty” and relax — but the penalty was never the expensive part.
2. There is no spreading. Unlike an inherited IRA, where a non-spouse gets up to 10 years to draw the money down, the inherited HSA has no multi-year option. The entire balance is income in one tax year, stacked on top of the beneficiary’s other income, often pushing them into a higher marginal bracket.

That single-year stacking is the real damage. A $92,000 HSA dropped on a beneficiary who already earns $100,000 doesn’t get taxed at their average rate — it gets taxed at the top of their bracket, and a larger balance can spill into the next one. For 2026, the 24% single bracket runs $103,351–$197,300 and the 32% bracket begins at $197,301. A single filer earning $100,000 who inherits $92,000 lands at $192,000 of taxable income — the whole inheritance stays inside the 24% band and costs about $22,080 in one year. Push the base income higher (say $115,000) and part of the $92,000 spills into the 32% bracket, pushing the bill toward $22,900 — the same balance, taxed harder, purely because of when it all hits.

The one lever a non-spouse heir can pull

IRC §223(f)(8)(B) gives the non-spouse beneficiary exactly one way to shrink the bill: they may reduce the taxable amount by the decedent’s qualified medical expenses that the beneficiary pays within one year of the date of death. If you died with $18,000 of unpaid or unreimbursed qualified medical bills, your child can pay those bills within 12 months and subtract $18,000 from the taxable HSA balance — cutting their income hit dollar-for-dollar. This is the move most heirs never hear about, and it is worth real money. Keep your medical bills and receipts findable so your heir can use it.

The estate default: usually the worst of the three

If your beneficiary form is blank, outdated, or names someone who predeceased you with no contingent, the custodian falls back to its default — almost always your estate. When the estate is the beneficiary, the full HSA fair-market value is included as income on your final Form 1040 (the decedent’s own last return), and the asset passes through probate.

Why this is typically worse than naming a non-spouse human:

• No one-year medical-bill offset. The §223(f)(8)(B) reduction for paying the decedent’s medical bills is available to a named individual beneficiary, not to the estate as a catch-all default.
• Probate exposure. The money sits in the estate, subject to probate timing, creditor claims, and administrative cost, before it reaches anyone.
• Possible compression on the final return. Depending on your other final-year income, the lump can land in a high bracket on your last 1040.

The blank beneficiary form is the single most common — and most avoidable — HSA estate mistake. It takes five minutes online with your custodian to fix.

Side-by-side: same $92,000 HSA, three beneficiaries

The spread between the best and worst result on one $92,000 account is more than $22,000 — decided entirely by a beneficiary line you can edit in five minutes.

Back to Margaret: the spend-down decision

Margaret’s spouse is deceased, so the tax-free spousal rollover is off the table. Her only heir, David, is a non-spouse who would owe full income tax on the balance. That changes the optimal strategy entirely — for her, the HSA is now a tax liability waiting to detonate on David’s return, and the best move is often to spend it down herself.

Margaret is 71, past 65, so her HSA already behaves like a traditional IRA: she can withdraw for any reason at ordinary income rates with no 20% penalty (IRC §223(f)(4) penalty does not apply after 65). As a single filer with ~$58,000 of income, she sits in the 22% bracket (single 22% band: $48,476–$103,350 for 2026). If she draws the HSA down over several years — spending on her own qualified medical and long-term-care costs tax-free, and taking modest non-medical withdrawals at 22% — she empties the account at her own lower rate instead of leaving David to pay 24% on the whole thing in one year.

Three concrete spend-down levers for a pre-death HSA when heirs are non-spouse:

1. Reimburse old receipts now. If she banked receipts for 20 years (the shoebox strategy), she can pull tax-free reimbursements today for expenses paid long ago — no time limit on when a qualified expense was incurred, as long as it was after the HSA opened.
2. Pay qualified long-term-care insurance premiums. HSAs cover qualified LTC premiums tax-free up to age-based limits — a clean way to convert HSA dollars into protection while shrinking the taxable balance.
3. Take measured non-medical withdrawals at her 22% rate. Better she pays 22% deliberately than David pays 24% involuntarily in a single stacked year.

What most people miss

The trap is treating the HSA like a Roth IRA in your estate plan. A Roth passes to heirs income-tax-free; people assume the HSA, with its triple tax advantage, behaves the same way at death. It does not. The HSA’s tax-free magic ends at the owner’s death for everyone except a spouse. A large HSA left to children is one of the most heavily taxed assets you can pass on — worse, per dollar, than a traditional IRA, because the IRA at least gets a 10-year drain window to manage brackets while the HSA is taxed all at once.

The second thing people miss: order of accounts to spend in retirement flips based on your beneficiary. Conventional wisdom says preserve the HSA and spend it last because of its tax-free growth. That is correct if your beneficiary is your spouse. If your beneficiary is a non-spouse, the HSA should often be spent earlier, not last — because every dollar left in it at death is a dollar your heir pays ordinary income tax on, while a Roth left to that same heir is tax-free. For non-spouse heirs, the HSA is your worst account to leave behind, not your best.

The decision lever

Pull up your HSA custodian’s beneficiary form today and answer one question: is the named beneficiary your living spouse, a non-spouse, or blank?

• If you have a living spouse you want to inherit it — name them, and only them, as primary beneficiary. That single line converts a future taxable event into a fully tax-free rollover under §223(f)(8)(A).
• If your heirs are non-spouse — still name them (never leave it to the estate), keep your medical receipts organized so they can use the one-year §223(f)(8)(B) offset, and flip your retirement spend-down plan to draw the HSA down during your lifetime at your own bracket rather than dumping it on them at theirs.
• If the form is blank or names someone deceased — fix it before you do anything else. The estate default is the most expensive way your HSA can be inherited.

One beneficiary line. Up to $22,000 of difference on a single account. It is the highest-leverage five minutes in your estate plan.
